COUPLING I 'OR PIPE, HOSE, SHAFTS, &o.

Specification of Letters Patent.

Appucation med June 2e, 1912. seriai No. 'z`os,o6o.

T0 all whom it may concern.' Be it known that I, ALFRED E. HYLAND, acitizen of the United States of America, and a resident of Barre, countyof Washington, State of Vermont,l have inventedy certain new and usefulImprovements in Couplings for Pipe, Hose, Shafts, &c., of which thefollowing is a full and clear specification, reference being had to theaccompanying drawings, in which-' Figure 4l is a side elevation of theclosed coupling; Fig. 2 is a half side-elevation and half longitudinalsection of the coupling box and pipe; Fig. 3 is an end view of thecoupling in locked position; Fig. 4 is a view of the two flange membersin assembled position; Fig. 5 is a view of the -housing of the couplingin open position; and Figs. 6 and^7 show the coacting faces of the twoflange' easily connected up t will be further seen that by myconstructlon members.'

My`invention is designed to produce a simple device for couplingpipes,`etc.,.the construction being such that an instantaneous and easycoupling and uncoupling may be effected without the useof a pipe wrenchor other tool.

In the drawing, B designates the two sections of pipe or other membersthat are to be coupled together and CC designate an annular flange whichis screwed or otherwise affixed to the end of each of said members, thisannular flange having its outer annularl'face DD ground to provide aclose jointv` andl also having its rear face or edge beveled at L toprovide an annular -cam surface. Each of these flanges is also providedon its circumferential face with 'a pluralityof transverse vribs Jextending practically the full width of the flange, the object of theseribs being to prevent injury by bruising of lthe faces L` and DD shouldthe pipe be dropped or thrown down in shi ment or handling. These ribsalso provi e a protection forv the faces during the act of screwing theflange tothe pipe or shaft.

The two ground faces DD of the flanges, when fitted together, form anabsolutely water-tight-joint, if ground true, and in order to pressthese two faces together rigidlyl provide a coupling box consisting oftwo semi-cylindrical members A which are adapted to entirely envelop thetwo abutted.

flanges; these two boxes being hinged together at E and having theiropposite abutt1ng edges clamped and locked together by a suitablequick-acting lever mechanism.

I prefer the form of lever mechanism shown, in which a curved lever F ispivoted to a lug I on one of the boxes, this lever being provided with acurved link Gwhich is adapted to engage over a hook-lug H -formed on theother box. With this lever and link device, it will be seen that asingle half turn of the lever locks the coupling firmly and holdsituntil released, and that'A by swinging the lever in the oppositedirection the locking device will be released and the two sections ofthe pipe or shaft will be free to be separated. It will be seen,therefore, that the coupling may be quickly and and disconnected, and itcorrosion or extremes of heat and cold will not interfere withinstantaneous locking or unlocking of the coupling.

The end Walls of the coupling box on their interiorare each providedwith an annular inwardly facing beveled face K which is adapted to fitagainst the adjacent similarly beveled face L on one of the flangesPatented Nov. 3o, 1915.

flange havin a front ground face and a rear annular beve ed face andalso having a plurality of spaced transverse ribs on its circumferentialface, a coupling box consisting of a pair of semi-cylindrical sectionsadapted to embrace the box, the interior 'of the box being provided withinwardlv facing annular faces adapted to engage the beveled innerends ofsaid flanges, and means for clamping the two box sections together.
